Abstract:

A system has been developed to detect epileptic seizures in real-time during long-term EEG LTEEG monitoring, LTEEG is an important clinical service provided by the Neurology Department at Christchurch Hospital to investigate patients who have relatively infrequent but recurring seizures over extended periods. The detection algorithm looks for extended amplitude and frequency changes, calculated using basic signal-processing techniques, followed by a rule-based stage which compares time-dependent features against dynamic thresholds for each channel, Spatial context is used to discriminate eye artifacts. The system was tested on EEG data from 5 patients containing 44 epileptic seizures, The sensitivity and selectivity of the algorithm were 88,7 and 92,6 respectively.
